There are:
mortal aasimar (planetouched origins, the equivalent of tieflings, usually of human ancestry)
Aasimari Devas (immortal angelic souls in a mortal humanoid form)
and "angelic devas" - celestial angels and servants of the Gods, usually separated into three different orders.
I am not sure if current lore really differentiates Aasimari devas and angelic devas anymore, though - the difference between them is... somewhat minimal and it gets confusing when they have virtually identical names.
Thank you, this clarifies my confusion over the aasimar thing. It makes more sense for Aylin to be a kind of celestial "daughter"/servant of Selune rather than a part-mortal like a Bhaalspawn, IMO.
